Question

What generic type should i use, if I have to assign a Character value to it?
For now I’m using type Char is(<>); at the generic declaration,
and assign the character value like this:

XY:GenericChar;
CharacterVariable: Character:='A';

XY:=GenericChar'Value(Character'Image(CharacterVariable));

It works, but i think there should be a better way.

Answer 1

You could use 'Pos and 'Val.

Converting between non-related enumeration types is non-trivial. Best would be to use a conversion function like:

generic
   type Generic_Char is (<>);
   with function To_Generic_Char (Source : Character) return Generic_Char is <>;
package Foo is
...

That way your generic package wouldn’t have to care about converting.

For instantiating the package you would have to create the function.
